Some devices (e.g. Qlogic iSCSI HBA hardware like QLA4010 up to firmware 3.0.0.4) initiates TCP with SYN and PUSH flags set. The Linux TCP/IP stack deals fine with that, but the connection tracking code doesn't. This patch alters TCP connection tracking to accept SYN+PUSH as a valid flag combination.
